Examples of instructions

1. Display data  (00 32 decimal is 50, and negative numbers are represented by the inverse code. If FF FE is sent, -001 is displayed)
2. Set the position of the decimal point the range is 01 – 03
   • 01 is the decimal point after the tens
   • 02 is the decimal point after the hundreds
   • 03 is the thousands, and only the tens and hundreds are displayed when it is negative
3. Set brightness (range 01-07, the larger the data, the brighter)
4. Set flash
5. Set the baud rate (data range 0 – 7 corresponds to 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200)
6. Set module address
